    Abstract: A method, system, and taggants (tracers) for quantifying zonal flow in a multi-lateral well having a wellbore with a first lateral and second lateral. The technique includes flowing first produced fluid from a formation via the first lateral into production tubing providing a first taggant through a first dosing tubing to the first lateral, and flowing second produced fluid from the formation via the second lateral into the production tubing and providing a second taggant through a second dosing tubing to the second lateral. A produced stream having the first produced fluid and the second produced fluid flows uphole through the production tubing and discharges from the wellbore. The produced stream may be analyzed to measure an amount of the first taggant in the produced stream and an amount of the second taggant in the produced stream.

    Abstract: A coated proppant including a particulate substrate, a first polymeric layer surrounding the particulate substrate, and a second polymeric layer surrounding the first polymeric layer. The first polymeric layer may include chemical additives. The second polymeric layer may include chemical tracers. The chemical tracers include barcoded degradable polymers, fluorescent dyes, quantum dot nanoparticles, superparamagnetic nanoparticles, up-conversion phosphors, long-persistent phosphors, time-resolved fluorescence resonance energy transfer polymer-nanoparticles (TR-FRET), or combinations thereof.

    Abstract: Compositions and methods for determining the origin location of subterranean rock samples. In some implementations, the compositions include a nanoparticle tag that includes a natural polysaccharide, a fluorescent dye, and superparamagnetic nanoparticles. In some implementations, a method of determining the origin location of a subterranean rock sample includes mixing the nanoparticle tag into a fluid, flowing the fluid into a subterranean formation, recovering subterranean rock samples from the formation, separating tagged rock samples from untagged rock samples using a magnet, and determining the origin location by analyzing a fluorescent signal of the nanoparticle tag.
